B. BEoKnIt, of

*New York city, county and'S'tate of New the bridge, and which will aiford sul'li'cient' g and rearwardly, thence bending upwardly,

York, have invented certain new and .useful Improvements in Eyeglasses; and I do here by declare the following to be a full, clear, and exact description of the same,ref'erenee;being had to the accompanying drawings, forming a part of the specification, and tothe-referw ence-numerals marked thereon,

My presentinvention relates to improvements in eyeglasses, andmore especially to that class wherein'relative movement of the lenses serves'to operate the nose guards, and

the object of the present invention is to'pro vide'a bridge spring for connecting the lenses that will permit] ample movement of the lenses-without unduly straining the metalof action to-firmly hold the eyeglasses in'proper position'be'fore the wearers eyes, the bridge presenting a neat appearance and capable of tions of parts'all as will'be hereinafter more fully described, the novel featuresbeingpointed out in the claims at the end ofthe specifi cation. I e In the drawings: Figure 1 1s a perspective view of a pair of. eyeglasses embor ying a bridge spring constructed in accordance with my present invention. Fig. 2 is'a I )lan view of the eyeglasses shown in Fig 1. *ig. 3 is a perspective view ofthe bridge springshownin the preceding figures, and the stud and guard separated therefrom, and Figs. 4. and 5 are perspective views of other forms'of bridge springs constructed in accordance withmy present invention.

similar'reference numerals 1n the several figures indicate similar parts.

. In the.present1nvent1on, instead of forming the bridge spring "with asingle strip ex tending between the studs or points of attachment as heretofore, a plurality of connecting portions are em loyedbetween the 1 points of attachment which will be subjected to bending action when the lenses 'are'manipulated to operate the nose guards, and the combined spring'a'ction-of the parts provides an ample and evenspring action for firmly holding the guards in engagement with the V wearers nose, the distribution of themetal ofthe bridge into several strips or; members reducing the internal stresses of themetal' incident to the hendin action and thus preventing breaka e. T 1e plural vconnecting.

bridge springalso enable the loops or resilient portions to be'arrangedandinembers the distributed among the members in different ways in order that the best action of the spring maybe secured;

" 'Thebridgespring shown in Figs, 1, 2 and 3 is shown applied to theordinary 'rimless eyeglasses embodying the lenses 1, having the studs or attaching devices 2 at their proximate ends, and the bridge spring in its press studs: The spr-ingshown' in these figures embodies a palr of members 3 and 4, the inembfer 3 in this instance forming an-upper ent form is adapted for attachment to these' portion havingits ends extending outwardly forwardly and downwardly to the stud, the

ends of this member of the bridge beingthus formed into loops or coils 5 arranged in vert cal plane s disposed transversely of the lenses and having their free ends adapted to be se-' cured in the boxes of the studs The lower member did the bridge in the presentform is preferablycurvcd to conform to that of the upper member and has its ends extending directly to thebo'xes ofthe studs at pointsrn rear of the attachedends of the upper mem-' her, and the ends'of both members are secured to the studs in any appropriate mannor, the nose guards 6 in the present instance being-fitted over the ends of the spring and firmly clamped against'them by means of the usual fastening screw 7. The spring shown in Fig. 4 embodies an uppermemberS which is preferably bowed forwardly in a horizontal plane, itsends extending rearwardly to the attaching devices,v and the lower nember 9 is provided with 'loops' or coils 1-0 formed therein by bending the material outwardly, forwardly,-inwardly.

and rearward'ly, the free .ends' ofthe coils thus formed being adaptedto be attached to lthe stud or attaching device! The spring shown in Fig. 5 is similar 'to that shown in Fig. 4,.although the resilient loop or coil is i The several-forms of springs, shown are formed of drawn stock and it is generally.

formed in the upper member 11 of the spring.

I afford sufficient firmness to support thelenses in pro er positions before the wearer's eyes,

said portions being provide the spring may be otherwise formed, and in I spring action to hold thenose guards firmly against the wearers nose while the other member of the spring cooperates therewith to and a so to limit the turning movement of .the lenses in opening the nose guards.

Eyeglasses provided with bridge springsoi the forms shown yield more readily in substantially a horizontal plane when the lenses are turned. to operate the nose guards, although the guards will be separated when the lenses are turned ina vertical'plane, or in planes intermediate the latter and a horizontal plane and inthe form shown in Fig. 1, the resilient portions-of the bridge are arranged above the studs or points .of attachment so that the separation oftheguards at all points is insured when the lenses are operated to re? move the 'ey'egla'sses, The action of the spring, however, may be varied by diflerent arrangements of the loops, coils or resilient portions. thereof, and a diflerent numberof connectingmembers maybe employed on the bridge as may be desired, and these members maybe either formed integrally or stood, and in some cases the same action may be obtained byla difierent arrangement of the-resilient-portions of the bridge. .Of course it willbe understood that, although-the bridges-inthe form's shown are made foiround'stock, the inventionis not so limited, as the springs may be made of'stockr of different cross sections, substantially flat stock being foundadvantageous in some instances.

I claim as my'invention; 1. In eyeglasses, the combination with the -lenses,'and nose-guards, of a bridge spring'attached to the lenses and having a plurality of resilient members adapted to span the nose and to permit relative turning movement of the. lenses-for operating the nose-guards the ends of the bridge being formed into eyes secured to the lenses.

2. In eyeglasses, thecombinationuwith the lenses, an d'nose-guards attached thereto, of a bridge. spring at-t-ached to the lenses and having an 'intermediate portion embodying a plurality, of nose spanning ortions, one of d with a resilient bend for permitting relative turning movement of the lenses to operate the nose-guards. 3. In eyeglasses, the combination with the lenses, and nose-guards attached thereto, of

members,.:oneof the latter being provide with resilient bends for permitting relative turning movements of t e. lenses, and the other memberbeing less resilient and serving to limit the turning movements of the lenses.

5. A bridge spring foreyeglasses embodying suitable attaching portions, and an intermediate portion embodying a lurality of nose spanning members, one oft e latter bemg provided with resilient bends for perm ttlng relative turning movements of the lenses. I I

6, A bridge spring for eyeglasses, embodying suitable attaching ortions, and an inter- 'mediate portion embo ying a pair of substantially parallel nose spanning members, one of said members being provided with a pair of resilient bendsfor ermitting relative movement between the enses. in separate parts, 'as W1 ll be readily under 7 Abridge spring for eyeglasses embodysuitableattaching portions, and an intermediate portion embodyin' a nose spanning -member provided'with res' ient coils for permitting relative movement of the lenses, and avsecond nose spanning portion extending substantially-parallel to the member first mentioned.

,8. In eyeglasses, the combination with the lenses having suitable attaching devices thereon, and-n oseguardsradapted to be attached thereto, ofa bridge spring embodying suitable attaching portions engaging the attaching devices of the lenses, and an intermediate nose spanning portion embodying a pair of substantially parallel members arranged above the'tops of the attaching devices, one of said members'being provided with a resilient portion for permitting relative turning movement of the lenses. 9. A bridge spring for eyeglasses composed of a single strip of material doubled to form :1 plurality of substantially parallel resilient nose-spanning members, and lens attaching eyes at the ends of the spring.
